Registration Dossier
Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
Data for the physico-chemical properties of vanadium and if relevant ferrovanadium (FeV80) were provided based on studies for the following endpoints:
(i) granulometry by laser diffraction and dustiness testing,
(ii) water solubility testing according to OECD 105,
(iii) flammability (screening test initiated with a representative FeV80 powder), and
(iV) density
The other endpoints (i.e. melting and boiling point) are based on handbook data and/or long time experiences in handling.
It is noted here that handbook data for physico-chemical properties are considered to be from a trusted source acc. to "ECHA, Guidance on information requirements and chemical safety assessment – Chapter R.7a: Endpoint specific guidance" and therefore, these data were considered reliable.
The results of the studies are reported in the endpoint summary as well as in the accompanying IUCLID database. Data for several endpoints were waived due to intrinsic properties of vanadium metal and/or based on the criteria as laid down in regulation (EC) 1907/2008 as described above.
Vanadium if produced in powder form is only produced as ferrovanadium. A representative ferrovanadium (FeV80) powder (D50=151.56 μm) could not be ignited with a flame in a test according to EU-Method A.10. It is concluded that vanadium metal powder with a particle size above 0.15 mm is non-flammable. Therefore, massive vanadium metal is considered non-flammable. The flammable properties of pure vanadium metal powder (if produced) with a smaller particle size need to be assessed on an individual, company-specific basis.
Based on handbook and new physico-chemical data that are included into this technical dossier, the vanadium metal does not need to be classified according to Directive 67/548/EEC and to regulation (EC) No.: 1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
